To understand the wrinkle resistance of Loose Knit Fabric, you first need to understand the selection of its raw materials. The raw materials used to make loose knit fabrics usually have natural wrinkle resistance:
Cotton fiber: Cotton fiber is soft and elastic, and can resist the formation of wrinkles to a certain extent.
Wool fiber: Wool fiber has natural curl and elasticity, which allows it to quickly return to its original shape after being subjected to external force, thereby reducing wrinkles.
Silk: Silk fiber is delicate and smooth, has good resilience, and is not easy to form lasting wrinkles.
Synthetic fiber: Synthetic fibers such as polyester and nylon usually have strong elasticity and resilience, which can effectively resist wrinkles.
Yarn processing
After the selection of raw materials, the processing of yarn also plays an important role in the wrinkle resistance of Loose Knit Fabric. The following are several key steps in yarn processing:
Fiber combing: Combing the fibers into uniform yarns to ensure the smoothness and consistency of the yarns, reduce the tension and stress inside the yarns, and thus improve the wrinkle resistance.
Yarn twist control: Appropriate twist can increase the elasticity and resilience of the yarns. Too high a twist will make the yarn tight and increase the risk of wrinkles; too low a twist will make the yarn loose, which is not conducive to the structural stability of the fabric.
Yarn refinement: Through steam treatment, softener treatment and other processes, the softness and elasticity of the yarn can be further increased, thereby improving the wrinkle resistance of the fabric.
The knitting structure of Loose Knit Fabric is the key factor in its wrinkle resistance. Knitted fabrics are different from woven fabrics and have unique elastic and structural characteristics:
Elastic structure: Knitted fabrics are composed of a series of interconnected needle loops, which have high elasticity and ductility. The needle loops can deform freely when subjected to external force, and can quickly return to their original shape after the external force disappears, thereby reducing the formation of wrinkles.
Loose weaving: Loose Knit Fabric has a low knitting density and large gaps between yarns. This loose weaving method allows the yarn to move and adjust freely when the fabric is squeezed or folded, reducing the formation of permanent wrinkles.
Various knitting patterns: Different knitting patterns such as plain needles, rib needles, and pattern needles not only give the fabrics different appearances and feels, but also affect their wrinkle resistance to a certain extent. For example, the rib knitted structure is tighter and more elastic, and can better resist wrinkles.
Post-processing
In order to further enhance the wrinkle resistance of Loose Knit Fabric, the finished fabric needs to undergo a series of post-processing processes:
Washing: Gentle washing can remove impurities and processing residues from yarns and fabrics, while relaxing the fiber structure and increasing the softness and wrinkle resistance of the fabric.
Softener treatment: Using a special softener to treat Loose Knit Fabric can lubricate the fiber surface, reduce friction between fibers, make the fabric softer and smoother, and thus reduce the formation of wrinkles.
Steam treatment: Through steam treatment, the fiber structure can be further relaxed, the stress and tension inside the fabric can be reduced, and it can be flatter and wrinkle-resistant.
Shaping: Through the heating and cooling shaping treatment, the shape of Loose Knit Fabric can be fixed, so that it has a stable size and shape while maintaining a soft texture, thereby improving wrinkle resistance.
